So went to work today and got yelled at and wrote up because I can’t pick up a 50 lb box not only because I’m pregnant but myself I physically can’t pick it up. The best part is if I go through the handbook the weight requirement is 25lbs. So idk what to do here the job sucks the pay sucks and I’ve been offered a better job should I just quit?
